I don't know this is a divider or elevation.please help me.
using styles? or what?

Try to add app:elevation="0dp" in your ToolBar.
Like this :-
<android.support.v7.widget.Toolbar
android:id="#+id/main_toolbar"
style="#style/MyDrawerArrowToggle"
app:elevation="0dp"
android:layout_width="#dimen/toolbar_height"
android:layout_height="#dimen/toolbar_height"
android:layout_alignParentRight="true">
</android.support.v7.widget.Toolbar>
Or you can use:-
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp">
</android.support.design.widget.AppBarLayout>

hopefully you will be helpe from it.

Actually the appbar is already having the elevation that's why it makes all the views to gets inside of itself.
So just you need to give app:elevation="0dp" to the appbar layout. It gives all other views freedom to stay over itself.

Issues with Coordinator Layout

I do not want the toolbar to collapse in the coordinator layout below. No matter what I do it collapses (the tabs do not collapse but the toolbar with the title does).
Second issue is that the nestedscrollview in the viewpager has a few EditTexts. On opening of softkeyboard when an edittext at the bottom is clicked the softkeyboard goes over the edittext. On closing the softkeyboard and then doing second attempt it successfully moves the edittext text up.

android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentScrim="#color/primary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:layout_width="match_parent"
android:layout_height="300dp"
android:scaleType="centerCrop"
android:src="#drawable/collapsing_toolbar_bg"
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_collapseMode="pin"/>
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/tab_layout"
android:background="?attr/colorPrimary"/>
</android.support.design.widget.AppBarLayout>
The atrribute:
app:layout_scrollFlags="scroll|exitUntilCollapsed"
prevents the collapsing toolbar layout from getting completely collapsed.
And replace android:src="#drawable/collapsing_toolbar_bg" with your image resource
